To all whom it may concern.-

Be it known that I, CHARLES LAMAR, a citizen of the United States, residing in Jackson township, in the county of Shelby and State of Indiana, have invented new and useful Improvements in Hoisting and Dumping A'pparatus; and I do declare the following to be a full, clear, and exact description of the invention, reference being'had to the accompanying drawings, and to the'letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to apparatus for hoisting bulk grain and the like from vehicles and delivering the same at an elevation from which such substances may flow by gravity into bins or elsewhere, as may be desired, the object of the invention being to provide inexpensive improved hoisting and dumping apparatus that may be easily operated by a man alone without requiring assistance from others, and which may be particularly well adapted for farm use, whereby wagons may be conveniently and expeditiously unloaded, as well as for use at elevators and side tracks of railways.

The invention consists in the peculiar construction and arrangement of parts, as hereinafter described and claimed.

Referring to the drawings,'in which similar reference characters designate like parts or elements, Figure 1 is an end elevation of the framework and apparatus, showing the front end of a wagon which is in position to be unloaded; Fig. 2, a fragmentary end elevation of the Windlass for effecting the hoisting operations; Fig. 3, a top plan of the hopper and chute into which the loadis designed to be dumped; Fig. 4, a side elevation of the dumping wagon-body and improved slings therefor, showing a trip-latch for the endgate of the body; Fig. 5, a fragmentary detail view showing portions of balancing devices for the slings; Fig. 6, a side elevation of the framework and apparatus and a wagonbody elevated as when being dumped, the running-gear of the wagon remaining on the ground; Fig. 7, a fragmentary perspective View showing a portion of the wagon-body and parts of the operating devices connected thereto, whereby the dumping may be efiected; Fig. 8, a top plan of a stop-collar em- Serial No. 154,743- (No model.)

ployed in tilting the wagon-body, and Fig. fl a fragmentary detail view showing the latch for the end-gate.

In this invention the wagon-body forms part of the apparatus, although it is adapted to also be used for general hauling either on wheels or on sled-runners.

In construction the supporting framework may be variously designed, and it may be either portable, as shown, or be permanently built in a barn, and in the latter case portions of the barn-frame and its floor may be utilized; but for descriptive purposes the portable frame is herein illustrated, in whichadesignates side sills; b, transverse sills; c, the posts set on the side sills; (1, side caps on the posts; e, transverse beams mounted on the side caps; f, arch-beams, and g a ridge-beam. A suitable pulley-block A is suspended from the ridge-beam g, although it may be supported by other suitable means above a point where a wagon may be placed. A suitable pulley-block B is hung to the other block A by means of a rope O, suitably reeved through the blocks. A slingbeam D of suitable length is connected centrally to the block B, and each end of the beam D is provided with a pair of sling-links E E, having suitable hooks at their ends.

A wagon-body F is adapted to be carried on wagon bolsters and is provided with eye plates h at the sides thereof, to which the links E E may be detachably connected. A

suitable Windlass, comprising a drum G and a frame H, supporting the drum, is secured near the place where the wagon is designed to be placed for unloading. The drum is divided about midway of its length bya flange 't' on its periphery, so that it may operate substantially as two connected drums for windin g ropes thereon. The drum is suitablyjonrnaled and is provided with a spur-wheel j and such other operative gearing and cranks as may be desired. The end of the rope C is secured to one end portion of the drum G. An independent rope I is also secured to the drum at the opposite end portion thereof and leads off from the side of the drum opposite to that from which the rope 0 leads, so that when either rope is being wound on the drum the other rope will pay out therefrom, and vice versa. A pulley 7c is suitably supported by one of the overhead timbers, and another pulley l is in like manner supported, the rope 1 extending from the drum over these pulleys and thence downwardly, the free end of the rope having a heavy counterweight J attached thereto. In order to prevent movement of the ropes and the loads thereon, when desired, a latch m is connected to the frame H and adapted to engage the spur-wheelj and prevent rotation thereof.

At suitable points two adjustable eyebolts K K are supported overhead by means of a beam 6, so that the bolts may be raised or lowered, and guide-links L L, which may be composed 'of rope, are attached to the eyebolts and extend to the ground-line, the links having hooks n attached to their ends, so as to be detachably connected to eyebolts p,

which are secured to a floor-timber, as b, and,

be held stretched. At the upper portions of the links L L they are provided each with a collar M, secured thereto, so that its position may be changed when necessary. Also the links are each provided with a movable bracket N, having an aperture q, through which the rope extends loosely, each bracket having a pair of holding-bars 'r 1", adapted to enter staples s s, that are secured to the sides of the rear end of the body F and be connected thereto detachably when required.

The rear'end-gate t of the body F is hung pivotally to the top portion of the body, so as to swing outwardly at the bottom thereof, and it is held in place normally by means of a catch 11,, attached to the gate, and a latch O, mounted on a pivot 11, connected to the bottom of the body F, the latch having a triparm w, projecting downwardly. Normally the latch 0 may be held in engagement with the gate by means of a pin :17, inserted removably in its upper end above the catch a, a suitable pin-hole being provided.

A hopper P, having a discharging-chute y,

is suitably supported in the framework at a proper elevation. The hopper has an inletchute Q, hinged at its bottom to the hopper in an opening therein and having sides 1 and 2 extending into the opening in the hopper. The chute may be drawn out radially, so as to be inclined below the wagon-body after the latter may have been elevated, and any suitable provision may be made for limiting its movements. It is provided with a suitable bracket R at its upper portion. The hopper has a pulley 3 mounted thereon, and an operating-cord 4 runs over the pulley and is-attached to the bracket, the cord extending from the pulley downwardly, so it may be reached by the operator, whereby the chute Q may be closed. Another cord 5 is also attached to the'bracket R and extends downwardly therefrom for opening the chute.

In some cases the wagon-body may be balanced by the operator while being elevated by means of ropes (not shown) connected to the ends of the body,as will be obvious; but the balancing is preferably accomplished by means of devices substantially as shown in 'Figs. 4 and 5, arranged either at one or both ends of'the'sling-beam D, the devices including a bracket S, secured to an end of the beam D and having a stud-axle 6, on which is rotatively mounted a pulley T, having a toothed quadrant U attached thereto, the latter being normally engaged by a pivoted pawl or latch 7, having an operating-cord 8. It will be understood that the beam D has a pulley T at each end thereof, although but one of them need have the quadrant and pawl devices. Each pulley has a rope or chain V hung thereon, having hooks 9 at its ends for connecting it to the eye-plates h. It will be obvious that the two pulleys T may be secured to a single shaft rotatively supported by the ends of the beam D, if preferred, so that one set of balancing devices may control both slingsVat both sides of the wagon-body.

In practical use the winding-drum G may be manually operated in a proper direction, so as to elevate the counterweight J and lower the hoisting-slings. The weight will then represent stored energy, the latch m being in engagement with the wheel j, whereby .the weight may be held up while the operator may be adjusting the other parts of the apparatus. The vehicle having the loaded body F thereon may be moved into a proper position either before or after elevating the counterweight. The slings with which the beam D may be provided may be connected to the body, and guy-ropes may also be connected to the body, if found desirable. The latch 0 may now be unlocked if it has been designed to be locked positively. The chute Q should be closed. If the vehicle is properly positioned, the ropes (or chains) L L will hang perpendicularly from their supports close to the staples s, that are attached to the body F, andv may be connected to the eyebolts 19. If found to be of unsuitable lengths, they may be readjusted by means of the eyebolts K K. The brackets N may then be moved along the ropes L L to proper positions and the bars 1" thereof connected to the staples s, and consequently with the body F. If the balancing devices are provided, the pawl 7 will engage the quadrant U and prevent r0- tation of the pulleys T while the load is being elevated, and when not employed guyropes may be used for the purpose. If new the drum be rotated in the direction opposite to that required when elevating the counterweight J, it will be apparent that the body F will rise and the weight J will descend, assisting the operator in his efforts, so that with simple hoisting devices with small power his strength may be materially augmented. The body F will rise until sufficiently elevated to permit the chute Q to open below the rear end thereof, when the rear end will be stopped by means of the brackets N, engaging the collars M, held by the ropes L L. The body may be now further elevated at its front end only, so as to be inclined, as in- IOO dicated in Fig. 6. If now the cord 5 be pulled downwardly, the chute Q will open and striking the arms to of the gate-latches will release the gate 1., which will be forced open .by the load, permitting the contents of the body F to run into the chute Q and the hopper P and then disposed of as may be desired. It will be understood that the pawl 7 should be disengaged at the proper time to permit the wagon-body to be inclined. After dumping the load the chute Q should be closed by means of the rope 4. While lowering the wagon-body F the weight J will again be elevated, ready for the next operation. Other movements and operations will obviously suggest themselves to the operator.
